Description

Technical Field

[0001] This invention relates to the field of grain harvester technology, and more specifically to an unmanned grain harvester with a vibratory bagging mechanism. Background Technology

[0002] A grain harvester is an integrated machine for harvesting crops. It can complete harvesting, threshing, and collecting grains in one go, or lay the straw of manually harvested rice, wheat, and other crops in the field and then use the machine to pick up and thresh it. However, in actual use, existing grain harvesters still have the following shortcomings; First, although existing grain harvesters have the function of harvesting and threshing grain, after threshing the grain, they only collect the grain in the storage bin for storage. In actual agricultural activities, the grain needs to be bagged, but existing grain harvesters do not have the function of automatically bagging grain. Secondly, when grain harvesters under the current technology place grain bags at their outlet for bagging, the actual bagging capacity is often lower than the maximum bagging capacity because the grain cannot be guaranteed to be tightly packed when the grain is discharged. And existing grain harvesters do not have the function of improving the tightness of the grain bagging. Therefore, in order to solve the above problems, there is a need to provide an unmanned grain harvester with a vibratory bagging mechanism. Summary of the Invention

[0012] The technical effects and advantages of this invention are as follows: This invention includes a bag-gripping mechanism. When the grain bag is transported on the transport assembly, its opening moves to the bottom of the suction cup. The bag-opening cylinder drives the suction cup downward to contact and adhere to the upper bag opening. Then, the bag-opening cylinder drives the suction cup upward to pull up the upper bag opening. After the bag opening is pulled up, the bottom bag opening remains aligned with the clamping gap of the clamping rollers. Driven by the clamping motor, the clamping rollers rotate in opposite directions, transporting the bottom bag opening into the bag opening groove of the clamping plate. At this time, the clamping cylinder drives the locking shaft to engage with the locking hole, securing the bottom bag opening in the bag opening groove through the locking shaft. Simultaneously, the bag-gripping motor drives the flipping shaft to move the swing arm. A ten-degree rotation brings the swing arm to a horizontal position. At this point, the clamping plate that secures the grain bag moves the grain bag to the bottom of the grain discharge hopper. The upper opening of the grain bag is pulled away from the suction cup by this movement. After being separated, the upper opening rests on the outer side of the conveyor belt under the action of the flipping motion. With the opposing rotation of the conveyor shaft and the clamping shaft, the upper opening moves into the groove of the clamping plate. The clamping cylinder drives the fixing shaft to engage with the clamping hole, thereby securing the upper opening. After securing the openings of both sides of the grain bag in the above manner, the grain can be discharged stably, thus achieving the automatic bagging effect of the grain.

[0013] This invention includes a bag-vibrating mechanism. When the grain bag is being filled at the bottom of the grain discharge hopper, the bag-vibrating motor drives the built-in shaft to rotate the cam. The rotation of the cam causes the arc plate and the bag-vibrating shaft to reciprocate, thereby making the bag-vibrating head reciprocate to vibrate the grain bag and improve the compactness of the grain bag.

In this embodiment, when the grain bag is transported on the transport assembly 6, its bag opening moves to the bottom of the suction cup 306. The bag opening cylinder 302 drives the suction cup 306 to move downwards to contact and adhere to the upper bag opening. Then, the bag opening cylinder 302 drives the suction cup 306 to move upwards, pulling up the upper bag opening of the grain bag. After the bag opening is pulled up, the bottom bag opening is still aligned with the clamping gap of the clamping roller 409. Driven by the clamping motor 410, the clamping rollers 409 rotate in opposite directions, transporting the bottom bag opening to the bag opening groove of the clamping plate 406. At this time, the clamping cylinder 415 drives the locking shaft 416 to engage with the locking hole 413, and the locking shaft 416 clamps the bottom bag opening in the bag opening groove. At this time, the bag gripping motor 403 drives the flipping shaft 401 to... The swing arm 404 rotates 90 degrees, causing it to move to a horizontal position. At this time, the clamping plate 406, which secures the grain bag, moves the grain bag to the bottom of the grain discharge hopper 2. The upper opening of the grain bag is pulled away from the suction cup 306 by this movement. After being separated, the upper opening of the bag will rest on the outer side of the conveyor belt 419 under the action of the flipping movement. Under the opposite rotation of the conveyor shaft 418 and the clamping shaft 420, the upper opening of the bag moves into the groove of the holding plate 417. The locking cylinder 423 drives the fixing shaft 424 to engage with the locking hole 422, thereby securing the upper opening of the bag. After securing the openings of both sides of the grain bag in the above manner, the grain can be discharged stably, thus achieving the automatic bagging effect of the grain.

[0027] Reference Figure 7 The bag-vibrating mechanism 5 includes a mounting box 501, which is fixedly installed at the bottom of the grain discharge hopper 2. An internal shaft 502 is movably sleeved inside the mounting box 501. A cam 503 is fixedly sleeved on the shaft of the internal shaft 502. A bag-vibrating motor 504 is fixedly installed on the outside of the mounting box 501. The bag-vibrating motor 504 is fixedly connected to the shaft of the internal shaft 502. The cam 503 is driven by an arc plate 505. Each arc plate 505 is fixedly connected to a bag-vibrating shaft 506. Each shaft of the bag-vibrating shaft 506 is movably sleeved with a sleeve 507.

A buffer spring 509 is provided between the bag-vibrating head 508 and the sleeve 507. The buffer spring 509 is sleeved on the shaft of the bag-vibrating shaft 506. In this embodiment, when the grain bag is being filled at the bottom of the grain discharge hopper 2, the vibrating bag motor 504 drives the built-in shaft 502 to rotate the cam 503. The rotation of the cam 503 drives the arc plate 505 and the vibrating bag shaft 506 to perform reciprocating vibration, thereby causing the vibrating bag head 508 to perform reciprocating vibration on the grain bag, improving the compactness of the grain bag.

[0028] Reference Figure 7 The discharge port of the grain hopper 2 is also equipped with a grain guide plate 201 to prevent grain from splashing outwards when it is discharged.

[0029] The working principle of this invention is as follows: When the grain bag is transported on the transport assembly 6, its opening moves to the bottom of the suction cup 306. The opening cylinder 302 drives the suction cup 306 downward to contact and adhere to the upper opening of the bag. Then, the opening cylinder 302 drives the suction cup 306 upward to pull up the upper opening of the grain bag. After the opening is pulled up, the bottom opening is still aligned with the clamping gap of the clamping roller 409. Driven by the clamping motor 410, the clamping rollers 409 rotate in opposite directions, transporting the bottom opening to the opening groove of the clamping plate 406. At this time, the clamping cylinder 415 drives the locking shaft 416 to engage with the locking hole 413, clamping the bottom opening in the opening groove through the locking shaft 416. At this time, the gripping motor 403 drives the flipping shaft 401 to rotate the swing arm 404 ninety degrees, thereby moving the swing arm 404 to a horizontal state. At this time, the clamping plate 406, which clamps the grain bag, moves the grain bag. At the bottom of the grain discharge hopper 2, the upper bag opening of the grain bag is pulled away from the suction cup 306 by the movement. After being separated, under the action of the flipping movement, the upper bag opening will rest on the outer surface of the carrying belt 419. Under the opposite rotation of the carrying shaft 418 and the clamping shaft 420, the upper bag opening moves into the groove of the holding plate 417. The locking cylinder 423 drives the fixing shaft 424 to engage with the locking hole 422, thereby locking the upper bag opening. After the bag openings on both sides of the grain bag are locked in the above manner, the grain can be discharged stably, thereby achieving the effect of automatic bagging of grain. When the grain bag is being bagged at the bottom of the grain discharge hopper 2, the vibrating bag motor 504 drives the built-in shaft 502 to drive the cam 503 to rotate. The rotation of the cam 503 drives the arc plate 505 and the vibrating bag shaft 506 to perform reciprocating vibration, thereby causing the vibrating bag head 508 to perform reciprocating vibration of the grain bag, improving the tightness of the grain bagging.
